Yes, good advice. It takes a lot of work to fill up a web, even a diddie. They need to be running 24/7 for any chance of making money. Mike

We have a 20 1/2" 6 color Diddie VIP UV press along with a two Diddie conventional presses. We use them along with two UV Rotateks to print continuous forms. The webs are not really my expertise I'm more of a sheetfed guy but I can provide some insight on your questions: Price- it's in the...

Might as well bring this back from the dead, we just bought 3 of the Techkon SpectraDens, all the bells and whistles. Love them, why we waited this long I have no idea. Easy to use and amazingly...a fully charged battery last more than 10 minutes and you can use them not plugged up to a power...

Humidity- this time of year can be pretty tough to keep it above 30%. Our pressroom stays around 50%, we have a massive humidifier unit installed inline with our HVAC system. It's a custom unit designed by the company that services our HVAC - ABM. We also have AMCO misters at the feeder and...

Not really sure what "half web" is. You need a roller lube, lot's of people make them, Bottcher, Anchor, or you can buy a relabed one like Spahira from Heidelberg. Their purpose is to keep the rollers cool and to help with cleaning. When you wash the lube you'll see ink and what not pulled out...

On a Heidelberg 6 color the units can't be disengaged per say. You can do things like change oscillation to zero, back off roller settings so they do not turn or if the unit will be down for 3 months (and you know the unit will be down no chance of using it)- take some of the key rollers like...

It's a long shot but once in a blue moon they pop on ebay along with other used Heidelberg parts.

Shut down for lunch??!!! no way.. not here Lunches are staggered, 2nd pressman watches the press while the lead eats. We have two helpers for three 40 inches presses- two 640's and one 8 color. Everyone takes turns and the presses stay running. The only time the press shuts down is to clean...

I've done it, it's a decent job and takes about 6 hours. A press that year the cam itself may no longer be available, in fact I'm pretty sure it's not. Our 98 sm102 required a completely new cam and lever assembly. The new cam was wider/stronger and the whole assembly more robust. When you...

We have a lot of QA procedures that are job and equipment specific. Sheets must be scanned into Image Control, LAB values recorded etc. Here's a few general ones that we use: Two person OK for every job, orginal ok sheet on display at the console at all times with Gray, LAB, and density values...

Our old presses with CPC 1.03 had a habit of acting up when the blue ribbon strips in the console came slightly loose. The pressmen would set the densitometer down in the same spot near where the key is located and eventually the boards underneath would come loose or the blue ribbon strip would...

7 days a week 24 hours a day and outsourcing about 200m sheets per month. We are always busy. The work is out there, it's all in what you do and how you do it. Edit- our sales force does not work off commission. Mike

We have 3 sm perfectors, one being an 8 color that we run coated 70# full coverage 4/4 work 24/7. Most pincer bars need to be rebuilt around 50 million impressions if running high quality 4/4 coated work, however the newer "eccentric" perfectors can go longer. What Heidelberg is doing is...

Luckily our power supply board was ok (they are not cheap). If you swap boards and the problem is still there it's definitely something controlled by that board. That's exactly what we did we swapped boards, saw the problem was still there and systematically unplugged and replugged all items...

Depends, I would expect a major press manufacture to have parts for at least 10 years. If not, then I would want something in writing from the manufacture stating "XYZ will no longer supply parts for this year of machine" etc. We've had issues with our older Heidelbergs in getting parts, some...

Do you have any errors on your console? They would show up as a yellow Circle T in the error display or possibly a 4 digit Dynamic Error Code under diagnostics? We hade a similar problem with our 8 color Ink Lines. The 5th unit blower bar motor would short out causing an error with one of the...

Yes, Al is correct high versus low air pressure is really how the system works. I mistakenly left that out of my post - the pressroom air above the sheet has greater pressure and that is what brings the sheet down. Interesting the principles behind something that seems so simple.

Ok, I looked through my notes because I remembered there is a specific reason why the venturi at the infeed can get clogged. I asking this question a few years ago when I was touring the demo room in Kennesaw. One of the engineers in laymen's terms explained to me the venturi system on the...

Thats a good question, we've seen it happen in a few different ways. We've printed certain jobs where we had to turn the venturi air down or even off to prevent the job from marking on the 2nd pass (we see this sometimes with specialty varnish jobs). At the end of the run going to the next job...

What year is your CD? If it's a feeder plus you have 3 filters underneath the infeed that need to be cleaned regularly. The older presses do not have the filters and the venturi holes requires some disassembly to clean them. Have you been running a lot of two pass work? The infeed venturi get...
